- i 13 Claims.

This invention is a novel improvement in storm windows adapted to be mounted in the frames of windows, french doors, or the like, preferably across the inside of the window or door frame, so that the same may be readily inif stalled and removed from the inside of the house or room. I,

The principal object of the invention is to provide a storm window of the 'above type which may be made either as a single panel or made in panel sections, each panel-section consisting of a transparent or translucent pane of glass or other desired material'of requisite rigidity'and of somewhat smaller size than the portion'of the window frame, which the pane is to cover, the pane having a resilient frame extendingfentirely around the periphery thereof consisting of sponge rubber having'a continuous slot in its inner periphery receiving the edges of the pane whichis secured therein by adhesive, and the sponge rubber frame having on its exposed side a coating or facing of hard rubber to render same impervious to air or moisture.

Another object of the'invention is to provide a storm window of the above type in which the panel sections, installed across the inside of the window or door frame, are maintained in position by novel clips which holdthe resilient frames of the panels in position, the clips being readily removable without injury to the panel frames or to the window or/door frame.

Other objects of the invention are, to provide a storm window of the above type in which the panel sections are provided with resilient frames, thereby eliminating rattling, and preventing marring of woodwork, said panels requiring no paint for upkeep, and being applied to the frames from the inside of the room or house require no ladders for installation; also a storm window which may be installed at any time of the day or night and'in any kind of weather; also a storm window which requires no changing in dimensions due to conditions of extreme dampness or dryness; also a storm window which will be'a positive seal by reason of the use of the resilient frames for the transparent pane, the seal eliminating condensation between the main window sashes and the storm panel; also a storm'window in which the amount of depth of the dead-air space can be varied within the limits of the trim of the window'paner Further objects of the invention are to provide a storm window of'the above'type which will be of light weight, and willrequire a minimum storage space; also a storm'window which canbe applied to curved windows; also a storm window which can be made in sections, eliminating the necessity 'of utilizing large one-piece storm windows; also a storm window which can be made by an unskilled workman without any need of special tools and installed in a fraction of'the time required for fitting wooden sash storm windows.

Still further objects of the invention are to provide storm windowswhich are very practical in connection with air conditioning of the house or room, and which will provide for cleanliness byeliminating seepage therethrough of soot and dust.

I will explain the invention with reference to the accompanying drawings, which illustrate several practical embodiments thereof to enable others familiar with the art to adopt and use the same; and will summarize in the claims the novel features of construction and novel combinations of parts for which protection is desired.

In said drawings:

Figure 1 is an elevation of a window frame looking at the inside face, equipped with my inside storm window.

Fig. 2 is an enlarged vertical section on the line 22, Fig. 1.

Fig. 3 is an enlargedtransverse section on the line 3--3, Fig. 1.

Fig. 4 is an exploded perspective view of the clip for holding the storm window in place in the window frame.

Fig. 5 is a section on the line 5-5, Fig. l.

The window frame'A is of usual construction, mountedin the wall Wof the building. in the usual manner, and provided with a sill S seated upon the bottom member of frame A, said frame being provided with the usual upper sash U and [lower sash L, running in guides provided there for, sashes U and L being adapted to normally close the window opening. Between the sashes U and L and the inside edge of the window frame A are strips G at the sides of the. frame A, forming the inner guide for the lower sash L, also a strip G of corresponding thickness extending across the top of the frame A, as shown inFig. 2, the strips. G and Grv terminating short of the inner face of the frame A, as indicated in Fig. 2 and serving as a backing for the storm window sashes, hereinafter described. The above construction is conventional in the majority :of window frames now in use, and forms no part of my present invention.

As-shown in Figures 1 and 2, my novel storm window preferably consists of an upper pane I and a'lower pane 2, preferably formed of glass or other rigid transparent or translucent material. -If desired, the sashes I and 2 may constitute a single integral pane. Sashes I and 2 are of somewhat smaller size than the opening in the window frame in which the storm window is to be mounted, and around the periphery of the sashes hand 2 is:a-=continuous-resilient:frame-3 of same shape as the=.pane, said frame 2:3 :b'eing preferably formed of sponge rubber having high resiliency and capable of being considerably distorted or deformed while normallymmaintaining its molded shape.

Around the inner periphery zefgrubberrfrzame 3 is a continuous groove 14 fewidth somewhat less than the thickness of-therpane's ..I1101122via-mii of considerable depth, the same preferably having a rounded bottom 4a, gas indicatedrinifi 3, and the panes I and 2 are preferably secured in the grooves 4 by means of shellac .orother adhesive, so that the riibber at the sides of the groove will adher -...tightly to :the ,gpames J sand .42.
